basic surgical tray

#3 blade handle, Adson 1 x 2 delicate tip forceps, Iris scissors 4 ½ curved serrated, 2 single prong skin hooks, 2 Halstead mosquito forceps 5” curved delicate tips, Webster needle holder 5” smooth jawed with tungsten-carbide inserts, Northbent suture scissors 4 ¾

Typical causes; coagulopathy (intrinsic or iatrogenic), inadequate intraoperative hemostasis, loose pressure dressing, exertion and/or manipulation of the wound site by the patient

Burrow’s triangle

triangle of tissue removed to facilitate rotation flap


Chalazion: useful for stabilizing mobile mucosal surfaces

composite graft

graft of skin and other appendage (hair, cartilage) ex: hair transplant autograft

donor sites: antihelix, inferior crus of ear helix, scalp, tragus


1-10 mm, round or oval

dermatomes, electric

Brown (Zimmer): most common

Padgett: cumbersome graft width adjustment, because uses shims

Simon-Davol: light, but only one setting (0.015 thick and 1 5/16” wide)

dermatomes, free hand

Blue blade, Weck knife

digital nerve block

lidocaine without epinephrine, use < 2 cc, may use EMLA

dog ear

AKA redundant edge tissue, standing cutaneous cone, triangular redundant tissue

donor site--graft site

superior retroauricular area/upper eyelid--lower eyelid,    lower retroauricular area--cheek/temple, preauricular area/lower lateral neck--mid cheek/chin,     supraclavicular area-medial canthus/lower eyelid,   upper lateral neck--helix,    glabella--chin/forehead/nose   inguinal fold/antecubital fold--hand,   nasolabial fold--nose


eutetic mixture of local anesthetics


1:100,000-1:300,000 epi:lidocaine.  Controversial (and routinely disregarded): avoid on ears, fingers, nose, penis, toes

forceps (pickups)

Adson: most common forcep, smooth, serrated, toothed (1 x 2), may have suturing platform

Allis: tightly grasping tissue for mobilization (cyst removal)

Bishop-Harmon: use for delicate tissue, 3 holes in handle, smooth, serrated, toothed (1 x 2)

Brown Adson: 7-8 grasping teeth per side to grasp heavy tissue

DeJardin: wide jaws, 8 teeth per side (horizontal) for cartilage

Iris: narrow handle, delicate tissue, smooth, serrated or toothed (1 x 2)

forehead flap

may involve supratrochlear artery

freer elevator

instrument for use in nail removal

full thickness skin graft

ex: dog ear graft

fusiform shape

3:1 ratio (except on back 1-1.5:1)

glabellar rotation flap


gold handles

tungsten-carbide inserts in instruments

acute/expanding; occurs within hours of surgery; edema, throbbing pain
stable; present days after surgery; evolve from amorphous to organized (firm) to liquified (dissolved). 

hemostats (snaps)

Halstead, Mosquito, Jacobsen


avoid use around eyes, ear canal (use povodone/iodine)

Typical rate in dermatologic surgery is 2-3%.  Observed 3-7 days after surgery with increasing erythema, edema, pain, and warmth.  Increased risk with contamination, trauma to the tissue, excess tension, presence of dead space.  Inadequate post operative wound care, patient colonization with potentially virulent bacteria (Staph aureus, MRSA). 

island pedicle flap

near nasal ala

kite flap

BCC: 4 mm  dysplastic nevus: 2 mm  melanoma: 1 cm  nevus: no margin

dye used to mark tumor margin, orientation

Mohs micrographic surgery

stepwise tumor removal with microscopic control allowing maximum preservation of normal tissue

Mohs micrographic surgery, indications

BCC: morpheaform, perineural, recurrent

embryonic fusion planes: nasolabial fold, columella, preauricular, postauricular

size: > 1 cm head & neck, > 2 cm trunk & extremities

tissue conservation: ear, eyelid, genitalia, lips

tumor type: malignant fibrous histiocytoma, microcystic adnexal carcinoma, dermatofibrosarcoma protuberans, merkel cell carcinoma

miscellaneous: scar carcinoma, immunocompromised


30° angle to save tissue

mucosal advancement flap

no subcutaneous stitches, use silk

myocutaneous flap


needle holders

Castroviejo: spring action, rotary clasp, very fine jaws for fine needles, occuloplastic surgery

Crilewood: similar to Webster

neuro-smooth: similar to Webster

Derf: similar to Webster

Halsey: similar to Webster

Olsen-Hegar: scissors behind jaws for cutting suture

Webster: most popular, variable length & fineness

O to H

eyebrow, rim of ear, (+/-)lip

O to Z
